Changing the Robots.txt file to stop it from Blocking all Web CrawlersHow to edit robots.txt file

The ROBOTS.TXT file is normally located in the website’s document root. Your preferred text editor can be used to alter the robots.txt file. We describe the ROBOTS.TXT file in this post, along with where to find and how to change it. The typical ROBOTS.TXT file sample is as follows:User-agent: *

Disallow: /

The User-agent attribute’s * (asterisk) symbol denotes that all search engines are permitted to index the website. You can prevent any search bot or spider from indexing any page or folder by utilizing the Disallow option. A search engine crawler cannot access any pages because of the “/” following DISALLOW.

You can add your website to Google or another search engine and enable the search engine to scan your website by removing the “*” from the User-agent and the “/” from the Disallow option. The steps for modifying the ROBOTS.TXT file are as follows:

1) Sign in to your cPanel dashboard.

2) Open the “File Manager” and navigate to the root directory of your website.

3) The ROBOTS.TXT file must be located in the same directory as your website’s index file. The following code should be added to the ROBOTS.TXT file before saving it.

User-agent: *

Disallow: /

By including the code below, you can also block a specific problematic User-Agent in the.htaccess file.

RewriteEngine On

RewriteCond %{HTTP_USER_AGENT} Baiduspider [NC]

RewriteRule .* – [F,L]

This is how you could accomplish it if you wanted to block many User-Agent strings at once:

RewriteEngine On

RewriteCond %{HTTP_USER_AGENT} ^.*(Baiduspider|HTTrack|Yandex).*$ [NC]

RewriteRule .* – [F,L]

Furthermore, you can worldwide prohibit particular bots. Please log in to your WHM to complete this.

After that, you must go to Apache Configuration >>. Include Editor >> Select “Pre Main Include” >> Choose the appropriate Apache version (or all versions) >> Enter the following code and click Update to have Apache restart.

<Directory “/home”>

SetEnvIfNoCase User-Agent “MJ12bot” bad_bots

SetEnvIfNoCase User-Agent “AhrefsBot” bad_bots

SetEnvIfNoCase User-Agent “SemrushBot” bad_bots

SetEnvIfNoCase User-Agent “Baiduspider” bad_bots
